What Alga Plus does
AlgaPlus (legal name: ALGAPLUS - Produção e Comercialização de Algas e Seus Derivados, S.A.) is a Portuguese aquaculture-biotechnology company founded in 2011 by two biologists and headquartered at the PCI Creative Science Park in Ílhavo, Portugal. The firm operates a land-based Integrated Multi-Trophic Aquaculture (IMTA) system that combines macroalgae cultivation with organic fish farming (sea bass and sea bream) using salt water on non-arable land reclaimed from former salt pans in the Ria de Aveiro. It maintains a complete in-house production cycle — hatchery/nursery, cultivation, and processing (washing, salting, drying, grinding, packaging) — for seven Atlantic macroalgae species: Ulva sp., Palmaria palmata, Gracilaria sp., Codium tomentosum, Porphyra dioica, Porphyra umbilicalis, Fucus vesiculosus, and Chondrus crispus, including a proprietary Atlantic Nori hatchery and a maintained BIOBANK.
The company's commercial offering is structured across four brands: Alga+ (bulk B2B seaweed biomass to European certified partners), Tok de Mar (BIO-certified consumer food products for organic retail and HORECA), Sea Originals (wellness and talassotherapy products for spas and hotels), and Algaessence (co-branded nutritional supplements with Allmicroalgae combining macro- and microalgae). It also generates revenue through custom biomass production and consulting services for macroalgae cultivation development. With exports to 20+ countries representing over 75% of volume, certifications across BIO (since 2015), HACCP (2016), COSMOS (2020), and V-Label (2025), and installed capacity of 200 tonnes/year on a 6,650 m² cultivation footprint, AlgaPlus positions itself as a European leader in BIO-certified, land-based Atlantic macroalgae production.
Revenue is generated primarily through one-time product sales of biomass and finished seaweed products in multiple formats (fresh, brined, dehydrated whole, flakes, powder) to food, cosmetics, animal nutrition, and retail/HORECA customers, supplemented by licensing/co-branding income via Algaessence and professional services revenue from custom biomass production and R&D consulting. Distribution combines direct-to-consumer e-commerce (algaplus.lojasonlinectt.pt), B2B bulk sales to European certified partners, specialized organic retail, and spa/hospitality channels, with marketing support from industry events, EU R&D consortium participation, and earned media coverage.

Alga Plus competitors and assessment
Company assessmentDirect peers
- Mara Seaweed: Scottish seaweed brand producing edible seaweed products for retail and foodservice. Comparable to ALGAplus's Tok de Mar brand in the consumer food seaweed category, with a similar focus on sustainable, traceable European-origin macroalgae for the UK and European markets.
- Atlantic Sea Farms: US-based kelp farming company operating in the North Atlantic, supplying sustainable kelp to food brands and retailers. Comparable to ALGAplus on kelp/nori cultivation, sustainability positioning, and supplying branded seaweed ingredients into consumer food channels.
- Acadian Seaplants: Canadian diversified seaweed company — one of the largest macroalgae producers globally — harvesting and cultivating seaweed for food, agriculture (biostimulants), animal feed, and cosmetics. Comparable to ALGAplus on multi-species seaweed production and downstream applications, with much larger scale and broader crop portfolio.
- Oceanium: UK-based seaweed biotechnology company developing land-based cultivation systems and seaweed-derived ingredients for food, pet food, and bioplastics. Highly comparable to ALGAplus on land-based IMTA technology and on the strategy of moving seaweed biomass up the value chain into ingredients and consumer products.
- Seaweed Solutions: Norwegian macroalgae company specializing in kelp hatchery, cultivation, and biomass supply. Directly comparable to ALGAplus as a European, land/sea-based seaweed producer with R&D consortia involvement; the two companies actively collaborate on the SølKelp project while competing for similar B2B seaweed buyers.
- The Seaweed Company: Dutch/Ireland-based seaweed producer supplying food, feed, and cosmetics applications across Europe. Comparable to ALGAplus as a multi-application European seaweed supplier with both B2B ingredient and B2C product lines and active involvement in EU R&D projects.
Emerging players
- Cascadia Seaweed: Canadian seaweed cultivation and processing company producing kelp and other macroalgae for food, agriculture, and ecosystem services. Comparable to ALGAplus on land- and sea-based seaweed cultivation and a focus on sustainability certification, though operating at smaller commercial scale.
- Bretagne Biotechnologie Marine (BBM): French marine biotechnology company developing bioactive ingredients from seaweed for cosmetics and health applications. Comparable to ALGAplus's Sea Originals and Algaessence lines on seaweed-derived bioactive ingredients for cosmetics and nutritional markets, particularly in France.
Broad incumbents
- CP Kelco (Ingredion): Global leader in hydrocolloid production (carrageenan, alginate, pectin, xanthan) sourcing seaweed biomass for extraction. A BROAD_INCUMBENT relative to ALGAplus: it operates at the downstream extraction/processing stage of the seaweed value chain and is both a potential large buyer of ALGAplus's biomass (especially Chondrus and Gracilaria species) and a long-term competitor for seaweed-derived ingredient sales.
Others
- Allmicroalgae: Portuguese microalgae (Chlorella, Nannochloropsis) producer co-branding the Algaessence nutritional supplement line with ALGAplus. A strategic OTHERS peer: directly named partner rather than a competitor, with complementary microalgae capabilities that extend ALGAplus's product portfolio into nutritional supplements.
